Copy
now the girl’s layer and process the picture applying the filters. It
must be done the same way we did with the background, without changing
the adjustments: 1) Filter – Distort – Ripple2) Filter – Stylize – Diffuse3) Filter – Blur – Gaussian Blur4) Filter ? Brush Strokes ? Spatter

Mark out the girl’s skin on the new layer and deviating a little from the edges (Polygonal Lasso Tool), erase it with the Delete button on the keyboard.

Now we have to renounce to the black patches on the girl’s hair: Selective Color.

Represent
on a new layer that must be situated upper than all the rest, the
snowflakes colored in blue-dark and situate them on the entire
background. If the snowflakes’ color is not intensive enough, you just
have to copy their layer.

Minimize the Opacity of the snowflakes till 44%. Represent then on a new layer, above the girl’s one a crown, having a ready brush too. Download it here: http://www.deviantart.com/deviation/25594369/ ?qo=7&q=by%3Aspiritsighs-stock&qh=sort%3Atime+-in%3Ascraps.
